How do CPT and HCPCS Level II codes function together in healthcare coding?

CPT (Current Procedural Terminology) and HCPCS Level II codes work together in the healthcare coding system to provide a comprehensive description of medical services and procedures. CPT codes primarily cover professional services, such as physician visits, surgical procedures, and other outpatient services, while HCPCS Level II codes are used for ancillary services, supplies, and non-physician services that are not included in the CPT coding system, such as ambulance services, durable medical equipment, and certain medications.

This complementary relationship ensures that all aspects of patient care, from the professional services provided by healthcare practitioners to the materials and supplies necessary for treatment, can be accurately captured and billed. By working in tandem, these coding systems enable healthcare providers to submit complete and precise claims for reimbursement, ultimately facilitating better healthcare delivery and record-keeping. This is why choice B is the correct response.
